Title: Rotary, positive displacement machine
Inventor: SCHMITZ LOTHER PETER
IPC: F01C1/08
Filed: 1990-05-05
Abstract: A rotary positive-displacement machine of the type having intermeshing lobed rotors, comprising first and second two-lobed rotors (22,24) mounted respectively in the two housing bores (14,16) for synchronous rotation. The first, valve rotor (22) has a hub portion which periodically occludes an outlet port (20) to control the generation and discharge of high pressure fluid from the housing (12). Each lobe (32) of the valve rotor (22) has a leading tip portion (34) which is radiussed so that it does not define a sharp edge. Each lobe (32) also has an outer flank, a major portion (1-2) of which is a convex curve, which is generated to correspond to the form of the tip (8-9) of the second, displacement rotor (24) and which merges with a convex arcuate portion (2-3) whose centre (38) is offset from the valve rotor axis (26). Furthermore, each lobe (32) has a trailing flank formed by a convex curve (4-5), generated to correspond to the form of the tip (8-9) of the displacement rotor (24), which merges with a convex arcuate portion (5-6), whose centre (42) is offset from the valve rotor axis (26), followed directly by a concave arcuate portion (6-7) whose centre (44) is also offset from the valve rotor axis (26). <IMAGE>   <IMAGE>

Title: Distributed temperature sensor
Inventor: HANSCOMBE PAUL ANTHONY
IPC: G01K11/22
Filed: 1990-06-28
Abstract: A distributed temperature sensor comprises an elongate ultrasonic waveguide having a number of zones along its length, each zone having a grating formed in it. This is typically achieved by incorporating uniformly spaced notches or bands (or collars) throughout the zone. The grating spacing in each zone is different, so that each grating reflects a characteristic frequency. This frequency varies as the temperature of the zone varies, so if wide-band ultrasonic pulses are launched into the waveguide, the temperature of each zone can be determined from the reflected frequencies.

Title: Touch sensitive device
Inventor: LIAO YORK
IPC: H03K17/96
Filed: 1990-09-24
Abstract: A touch sensitive pad consists of a number of electrically conductive pads 10 surrounded by a conductive pad 11. Each pad 10 is connected via a respective capacitive blocking filter 12 to a multiplexer 13 and thence to oscillator 14. When touch pad 10 is touched directly to effectively bridge between one of the pads 10 and the surrounding pad 11, a change in effective impedance is detected by a resultant variation in the frequency of the oscillator 14. Filter 12 serves to prevent static electrical charges being applied to the oscillator input and filter out d.c. components and electrical noise from a finger applied to the pad. Conductive pad 11 may be omitted. <IMAGE>

Title: Servomotor piston movable to three predetermined positions
Inventor: WAGNER GERHARD
IPC: F15B11/12
Filed: 1992-05-13
Abstract: In the position of valve 28 shown pressure fluid from line 22 passes to working chambers 3, 4 on either side of piston 11 while chamber outlets 15, 16 are connected to reservoir 20. Thus the piston moves to a central position in which it closes outlets 15, 16. When valve 28 is moved to either of its other two positions outlets 15, 16 are shut, a chamber on one side of the piston is connected to the pressure source while the chamber on the other side is connected to reservoir 20. Thus the piston moves to one or other of its end positions. <IMAGE>

Title: Delta-sigma modulator with low thermal noise performance
Inventor: THOMPSON CHARLES D
IPC: H03M3/00
Filed: 1993-03-12
Abstract: An analog-to-digital converter includes a two-bit delta-sigma modulator having a first stage integrator (10) that feeds a noise shaping circuit (18). The output of the noise shaping circuit (18) is input to a two-threshold ADC (20) to provide the two-bit output which is input to a digital filter (22). The output of the ADC (20) is also fed back through a three-level DAC (24) to a summing junction (12) on the input of the integrator (10). The three-level DAC 24 has three output states with one state being a "do nothing" state. The thermal noise performance of the delta-sigma modulator as a function of the quantizer threshold voltages of the ADC (20) is first simulated and then the value of the quantizer thresholds is selected to provide optimum signal-to-thermal noise performance. <IMAGE>

Title: Polymeric mouldings reinforced with tows of fibres
Inventor: THICTHENER EDWARD PHILIP
IPC: B29C70/20
Filed: 1992-10-30
Abstract: An electrically conductive product of settable plastic material reinforced with non-conductive fibers is formed by drawing tows of non-conductive fibers through a bath of resin containing conductive fibers. Use of conductive fibers having a mean aspect ratio exceeding 100 permits the weight of conductive fibers to be under 2 %. Expulsion of resin during molding of a settable resin reinforced with fibers is prevented by pinching of the tows of fibers at least at one end of a die. This permits higher pressures to be used during molding.

Title: Scanning fire detector
Inventor: ISHIDA HIROSHI
IPC: G08B17/00
Filed: 1995-08-01
Abstract: A fire detector is provided with a scanning unit 101 which scans horizontally and vertically for infrared light, utilising a look up table of threshold intensity versus vertical scanning angle to determine whether the light has exceeded a predetermined threshold intensity. Upon detecting infrared light exceeding this threshold, horizontal scanning is stopped leaving just a vertical scanning function which analyses a frequency of the detecting signal though the vertical scan to judge whether the detecting signal is being caused by the fluctuation of a flame. Upon recognising that there is a fire, an extinguisher 150 is aligned with the horizontal stop position of the scanner and an electro-mechanical valve 204 is opened thereby directing water towards the flames. Further embodiments include the use of two sensors to reduce errors due to sunlight or artificial light. <IMAGE>
